A woman jumped to her death earlier today off a swank West Side hi-rise, authorities said.

The victim – who hasn’t been identified – leapt just before 9 a.m. from one of the upper floors of 505 West 37th Street near Tenth Avenue, authorities said. The luxury apartment building is located a block from the Javits Convention Center.

She was pronounced dead at the scene.

The impact of the woman’s fall was so powerful that it split the concrete sidewalk where she landed.
